Re: Clean-up on Logout

[Philip Wachtel <su...@wachtel.us>]

Hi there,

I'm picking up this thread after it's been sleeping for a while.

I have a javax.mail.Store object stored in temporary storage in my CustomTurbineUser object.  A screen sticks it in there upon login.  I've implemented my a new LogoutUser class (CustomLogoutUser) that has similar logic before it calls super.doPerform().  This works well.  However, if a session times out, I still want the mail store connection to be closed.  

My CustomTurbineUser object (see below) implements HttpSessionListener and I know that the sessionDestroyed() method gets run upon session timeout.  However, by the time it gets run, the user no longer seems to have the temporary data in it.  In other words, the Store object that should be returned with this.getTemp("imapStore") is null.  After the session is destroyed, my IMAP server still sees the connection.

Any idea how/where I can implement this code so that it will have my temporary data available to it?

Thanks much!
Philip

public class CustomTurbineUser extends TurbineUser implements HttpSessionListener {

        public void sessionDestroyed(HttpSessionEvent httpSessionEvent) {
        //HttpSession httpSession = httpSessionEvent.getSession();
        //httpSession.
        log.debug("@@@@@@@@@@@@@@@@@@@@@@ Destroying a session! @@@@@@@@@@@@@@@@@@");

        if (this.getTemp("imapStore") != null && ((Store)this.getTemp("imapStore")).isConnected()) {
            log.debug("User has an imap Store in his session.");
            Store store = (Store)this.getTemp("imapStore");
            try {
                store.close();
            } catch (MessagingException me) {
                log.info("Was not able to close imap connection: " + me.getMessage());
            }

        } else {
            log.debug("User did not have an imap Store in his session.");
        }
    
    }

}
